Thirty- and 50-microg microspheres containing latex-derived angiogenic fraction injected into the vitreous cavity induced retinal neovascularization in rabbits.
The intravitreal injection of microspheres containing the LAF can induce rubeosis iridis in rabbits and could be used as a simple experimental model for iris neovascularization.
An 83-year-old previously healthy woman arrived at the emergency department with a one-day history of intense abdominal pain in the epigastrium after eating. Generalized peritonitis was observed on physical examination; the patient had a pulse rate of 135/min, blood pressure of 86/40 mmHg and DATE OF SUBMISSION: IMAGING IN MEDICINE respiratory rate of 23/min. Computed tomography of the abdomen showed small bowel loop densification, pneumoperitoneum, jejunal diverticulum without inflammation signs, and a foreign body (Figures A-C). A small piece of chicken bone was found within the jejunal diverticulum (Figure D).FIGURE (A) CT of the abdomen (coronal view), portal phase after intravenous administration of contrast showing regular parietal thickening in the jejunum segment (arrows) locoregionally associated with densification of its respective mesentery (arrowheads); (B) CT of the abdomen (axial view, lung window) showing intraperitoneal free focuses in an accentuated hypoattenuation representing pneumoperitoneum; (C) CT of the abdomen (coronal view) showing high-density linear image within the jejunum segment, seemingly extending along its wall in the mesenteric side (foreign body); (D) Resected intraoperative specimen showing a jejunal diverticulum perforation by a chicken bone. In the upper right corner, note the chicken bone size in relation to the size of the scalpel handle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
